Text to ASCII Converter Online

Converting text to ASCII codes

This tool outputs the numeric code of every character in an input — the value used to represent that character internally.

For letters of the basic Latin alphabet those values fall in the classic ASCII range; accented and special characters sit above it.

How to use it

Paste the text and copy the sequence of numbers. Values appear in the order of the characters.

Note that spaces and line breaks have their own values and are included in the output.

What it is useful for

Helpful when hunting bugs in text data: it reveals invisible characters that break processing.

It is also useful for learning how character encoding works, since character and value sit side by side.

Frequently asked questions

Are accented characters supported?

They fall outside the original ASCII range. Their code value is output and it will be above 127.

How do I spot invisible characters?

They show up as extra numbers with no visible character in the text — a frequent cause of otherwise inexplicable errors.

Can I reverse the process?

Yes, with the tool that turns ASCII codes back into text.
